ALAMEDA, Calif. (AP) — The Oakland Raiders added another unproven quarterback to the mix, selecting Arkansas’ Tyler Wilson after trading down in the fourth round of the NFL draft on Saturday.

Wilson joins a quarterback room that already has Matt Flynn, acquired earlier this month in a deal from Seattle, and third-year pro Terrelle Pryor. Oakland traded former starter Carson Palmer to Arizona after acquiring Flynn as the rebuilding team has turned to the future.

Wilson was considered one of the top prospects after throwing 24 touchdown passes and only six interceptions while leading Arkansas to an 11-2 record in 2011. Wilson decided to stay in school for his senior season, but his draft status fell as the team struggled following the firing of former coach Bobby Petrino, who was embroiled in a scandal for hiring his mistress to work in the athletic department.

Wilson completed 62.1 percent of his passes while throwing for 3,387 yards with 21 touchdowns and 13 interceptions last season. The Razorbacks went 4-8 under interim coach John L. Smith.

Flynn is expected to begin the offseason as the starter but the Raiders have stressed that there will be competition at all positions. Flynn had expected to be the starter after signing as a free agent with Seattle last season only to be beaten out for the job by third-round rookie Russell Wilson. That led to his eventual trade to Oakland and Flynn hopes he doesn’t lose out to another rookie Wilson this year.

Flynn has made only two starts in his career, while Pryor has made just one. Pryor was late owner Al Davis’ final draft pick when he was taken in the third round of the supplemental draft in 2011. Now instead of being groomed as the quarterback of the future, Pryor will be fighting just to keep his spot on the team.

Wilson is just the fourth quarterback drafted by the Raiders since 1993, following No. 1 overall pick in 2007 JaMarcus Russell, 2005 third-rounder Andrew Walter and 2001 second-rounder Marques Tuiasosopo in 2000.

The Raiders have had a poor history when drafting quarterbacks, with the only real success since the start of the common draft in 1967 being 1968 second-rounder Ken Stabler, who led the franchise to its first Super Bowl title following the 1976 season.

The Raiders traded down 12 spots in the fourth round before taking Wilson 112th overall, adding a sixth-round pick from Tampa Bay in the process. Oakland moved down in the round after Philadelphia jumped up to take quarterback Matt Barkley with the first pick in the fourth round. The New York Giants then traded ahead of the Raiders to take Syracuse quarterback Ryan Nassib before Oakland took Wilson.

Oakland has four sixth-round picks and one seventh-rounder left on Saturday.
